David & Fred,

First off, I want to thank both of you for showing up for the SEA SAWG meeting today, where we were discussing the RASIM updates.  To be as clear as possible (always a challenge) our intention is to create what is now crafted as a Green Book, i.e. descriptive materials, that can be used as a reference for describing a wide variety of information systems.  We could decide to turn this into a Magenta Book (best practices, with more formalism), but I think we are going to stick with the GB format while making it as “normative” in form as possible.  A fine line, and possibly a fuzzy distinction.

David’s DAI team is intentionally creating a normative, directly implementable, Blue Book.  The true test of a Blue Book is whether it is sufficiently clear and unambiguous such that two entirely separate implementers can use the book to design a build a pair of systems that will interoperate successfully.  And that the services they deliver operate as expected.  To do this a Blue Book must contain requirements, stated in shall (and possibly may) language.  And Blue Books must contain a Prototype Implementation Conformance Statement (PICS).  This PICS lists, in concise form, all or the required and optional features of the protocol (or other standard).

As a part of the BB process these implementations, and the testing process and results, are to be documented in a Yellow Book of the form “Implementation test report”.  It is suggested that the format of the test report use the PICS as an outline of features to be checked and verified, and that a filled out PICS, reflecting  which features each implementation actually contained be a part of the test report.  This is all supposed to be part of the test report Yellow Book.  But the details to be implemented must all be specified in the BB.

So, note to Fred, what CONFERS should be looking at is the BB, and possibly the GB.  The YB will (or should) only provide info about the test configuration, the two implementations, and the test results.

I hope this is clear.

Cheers, Peter

Thank you. I'll start reading.
By the way, I spend a good bit of time in Lagos, PT and am trying to get the Portugues Space Agency to participate in something a little more "international" than having local meetings of what ESA is doing. Mind if I share this with them? As information, not as an invitation.

Hi Fred

Yes, we are working on a Yellow Book, based on whatever examples we could get from the CCSDS Publications page – however I believe that many Yellow Books have not been published. It is rather skeletal at the moment but our colleague from ESA will be adding flesh to the bones in the next few months, as the Blue Book gets closer to finalisation, and hence the various independent implementations are finalised.

DAI will be discussing this in our weekly videoconference tomorrow. I will ensure I have the latest version of the Yellow Book.

The current snapshots are as follows – as shown in the agenda to our meeting I just sent out:



Meeting: 10:00 Tuesday (Washington DC time),   1500 UK time, 1600 Paris time.

We started on the Green Book, to explore concepts, and the Magenta Book, to start to flesh things out. Now the Blue Book is (I hope) getting close, during which time we focussed down on areas, but of course the Magenta and Green books will need to be updated to be consistent with the BB where they overlap on specifics.

Regards

Subject: David mentioned a yellow book...

Did I hear correctly that there is a yellow book draft for an execution of information exchange for the purposes of interoperability under CCSDS?

I am interested in following up on this idea with the possibility of performing an On-Orbit Servicing mission demonstrating two spacecraft interoperability.

I think we might be able to get CONFERS (satelliteconfers.org<https://urldefense.us/v3/__http:/satelliteconfers.org__;!!PvBDto6Hs4WbVuu7!OO09CNJa_f73Q5wcp2Jwf_uA7GphswEp4rzuKPLB-9pgFAOnMFA8XIwUTXJYQ46zxyM1IgWxuPDTBGSequpFmmZV$>) to agree to execute a demo mission under a CCSDS umbrella (we would need to find a sponsor).

Can we follow the path of the new draft yellow book? How?

Fred
